HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 249,854, dated November 22, 1881,

Application filed July 29, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES A. MILLIKEN, of Biddeford, York county, State of Maine, have invented an Improvement in Heating-Stoves,

of which the following descriptiomin connection with the accompanyingdra wings, is a specification.

This invention has for its object the produc tion of an economical heating-stove provided [0 with chambers for warming cool air and discharging it again into the room. The products of combustion, instead of passing directly into a pipe and to the chimney, are made to pass down through the lower part or base of the stove, from whence they rise into the pipe leading to the chimney.

- Figure 1 represents, in side elevation and partial section, a stove embodying my invention Fig. 2, a partial vertical cross-section of the base on dotted line a: m; Fig. 3, a horizontal section of the base, showing the main central and side fines; and Fig. 4 is apartial rear elevation, showing the outer plate forming the air-chamber c.

The cylinder or drum (1, provided with any usual or suitable lining and grate, is extended above the enlarged ash-pit portion 1), which re ceives the ash-pan and ashes. Somewhat below the floor-plate b of the ash-pitportion b, I have made a floor-plate, d, which I have divided by partitions oh i, so as to form a series of lines, 0 e 6 and an air-space, c, the latter being between the bottom of the ash-pit portion and the top of the plates g h 2', herein shown 5 as arched. (See Fig. 2.) The flue e is in communication at its rear with the downflue Z in the pipe it, so that when the damper m is up, as in full lines,Fig. 1, the products of combustion pass down the flue I, along flue 6, out from its front endinto the fines c and c to the back of the base of the stove, thence up the risingflne n, and out atn into any suitable pipe leading into the chimney. During such passage of the products of combustion the said pro- 5 ducts act to heat the air in the air-chamber 0, fed by cold air at the openings 0, and such heated air rises into the space 0, from which it flows into the room through the registerspaces 0 (See Figs. 1 and 4.) So, also, the products of combustion heat the air which rises in the air-pipe spacep, permitting the discharge of air therefrom through the opening 19 (see Fig. 1) into the room. When the fire is first started the damper or will be turned down, as

in dotted lines, and then the products of combustion will pass through a hole in the division-plate r and out at exit W.

A stove constructed as described will throw 0d a large amount of heat in proportion to the fuel consumed, and will in its air-chamber 0 and pipe p warm agreatquantity of external air and project it upward and outward into the room, and the products of combustion leaving the stove at the exit-openimggm will have substantially all their heat abstracted.

I claim- 1. A heating-stove composed of a cylinder,

a, an ash-pit portion below the said cylinder,

a base below and separated from the ash-pit by a plate, said base containing an air-chamher, 0, an outlet for air heated in said chamber, and smoke-fines ee 0 and a divided pipe,

1?, leading by one division from the cylinder to the base smoke-fines, and thence by the other division to the chimney, the whole combined and arranged to operate substantially as specified.

2. The cylinder a, ash-pit portion 1), base portion composed of side pieces, floor-plates 11 d, partitions therein, arranged as described, to form an air-chamber, c, and flues e c 0 combined with the air-space 04 at the rear of the ash-pit portion b. the air-chamber 0 being provided with openings for the reception of air, and the chamber c with other openings for the discharge of heated air from the chamber 0, substantially as described.

In testimony whereot'l have signed my name to this specification in the presence of two subscribing witnesses.

JAMES A. MILLIKEN.
